To all wficm it may conce n:

Be it known that l, illici citizen oi. the United States Soivziy, in the county of @1101 lugs and State of New York have invented new and. useful.

Improvements tic-curing lelenus ilfor l llec trio-Lump Sockets tllltl tic Lille of which the following is n spcc i ution.

My invention relates to u securing means for electric lump sockets and the like provided with porce ain bodies hsving particular employment in the attachment of such articles to the object thereof being to provide it securing means which may be permanently attached to the porcelain bod es in u conveniant and economical manner with the minimum lia.hility oi seeirieu-rul letcclimerit, of the parts" [1. v LJAOSSLEX 7 ll,

it will be understood that in 1 I this class it is conunercinlly essential that tho securing parts he so initially sci'zurcrl in pa;- sition on the porcelain bodies that the screw or threaded bolt as is ordinurily eniployetl in attaching these articles to signs, will engage such securing part connecting therewith merely upon manipulation of the screw, (lrdinarily this securingpart isc securing nut of rectangular form and retained a recess in the body by a suitable cement. 3Q Cement however When so employed has proven to be susceptible to crooning and loosening during the repeated and. none too arei'ul handling which the articles are subjcctecl to under ordinary eonc'tions permitting line nuts to fell out, lost, and other inconveniences which are especially objeo tionsble when handled in l 5e quuntit My invention consists in the employment of a special peculiarly formed scouring not provided with extensions adapted to engage shoulders formed on the porcelain body in such manner that it will be permanently secured to the hotly without the employment of cement, suecess llly overcoming the diss Yuntn cs thereof. ln the accompanying drawing my invention is shown employed to secure e lamp socket to metal sign plate and the 1 'erence numerals of the description indicate 5Q corresponding parts in all the figures thereof.

In the figures my invention shown in 6:) connection with an electric lump socket having the body portion 1 of porcelain proidcd with oppositely arranged su' 'yoorting legs 2 2 and the insulating shoulder 23. On

'lhis securing means consists of the internally threaded nut ll adapted to 8 rest on the upper surface of the lug to be engaged by the. screw 1.0 as l'lCSt shown in Figs. l and 5 whereby the socket securely attached to he plate.

l t being essential, as utorcsnil that the s curing pert be POlH'ltlllOUtly f (('IIl'C(l in poon the socket tor this purpos the smon nuts 'l-l are orovidml with lhc integral extensions l5-l5 which n'llord :1 sin'iplo l1olr ing moans therefor that inn be easily formed in the slampir; operation {is best shown in Figs. 4- und :3 (no scouring is :10-

-complishcrl by the outwardly lwnliing' of the extension tips, to engage suitable projections or shoulders 'lonneil on the socket in such inin'mer that they are held' from withdrawal. Two 01'? these extensions are preterubly provided oppositelv arranged and bent downwardly into the in;- recess which is fornictl as best shown in i 2 fl. and 5 to receive them; the recess being provided withside enlargements ii For the accommodation of the extensim'ls which ni'e proton ably: larger at the bott znn th s coi'lvcnicutly forming the shoulders Illi to he engaged by the bent over extension tips 1818 and furthermore permitting the insertion of a suitable tool for so bending over the tips.

I have thus provided securing means which may be easily and economically stamped as an integrality and by the employment of which, electrical sockets and like articles may be securely clamped to the plates of signs etc. merely upon insertion of the screw the engaging part therefor being securely held in position upon the socket, being independently clamped to the socket in a permanent and secure manner, insuring against accidental detachment and the accruing inconveniences therefrom.

Having described my invention, what I claim is L'A securing means for electric lamp sockets and the like comprising a securing bolt and an engaging nut therefor provided with opposite integral downward extensions having their tips outwardly bent to clamp the nut in position' on the body.

2. The conibinat'ipn with a porcelain body and a securing means therefor, said securing means comprising. a bolt and an engaging nut for the bolt provided with fingerlike extensions depending therefrom and said body being recessed to receive said bolt and extensions said recess being enlarged to form shoulders to be engaged by the extension tips and to give access to bend over the tips permanently to clamp the nut on the body.

3. In a securing means for devices of the character described, a nut adapted to be secured in position on a wall of the device, said nut having integral portions at one end to engage with one surface of the wall, tips extending substantially at a right angle to said portions to engage with opposite surfaces on the wall and a screw threaded hole in the nut between the extensions.

4. A securing means for devices of the character described, consisting of a securing bolt and of a nut; said nut consisting of a fiat body having a threaded aperture to receive the bolt, opposite portions on the body to engage with one surface of the wall of the device to which the nut is applied, and opposite downward extensions on the body having tips bent to engage with an opposing surface of the wall.

. 5. In a securing means for electrical de vices, a nut adapted to be applied to a perforated lug on such a device, said nut being of sheet metal and having a flat main portion larger than the aert'oration to engage with one side of the lug and having opposite extensions downwardly extending at a ri ht an le to the main )ortion into the g g l perforation, said extensions having tips bent outwardly to engage with shoulders in the perforations and said main portion having a central threaded hole to receive a bolt.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.'
